BED-SPRING.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed February 18, 1908. Serial No. 416,543.

the following is a specification, reference being had to theaccompanying drawings.

Our invention relates to improvements 1n bed springs and moreparticularly those especially designed for the use of invalids andhaving adjustable head sections.

The object of the invention is to provide a device of this characterwhich will be simple, strong, durable, and comparatively inexpensive inconstruction and which may be readily adjusted so that the head sectionmay be supported at any desired inclination. lVith the .above and otherobjects in view, the inventionconsists of the novel features ofconstruction, and the combination and arrangements of parts hereinafterfully described and .claimed, and illustrated in the accompanyingdrawings, in which Figure 1 is a top plan view of our improved bedspring; Fig. 2 is a vertical longitudinal section taken on the planeinclicated .by the line 2-2 in Fig. 1; Fig. 3 is a vertical transversesection; Fig. 4 is a detail section taken on the plane indicated by theline 41 in Fig. 1 and showing one of the fasteners for retaining theadjustable or spring frame upon the bedstead or stationary frame; Fig. 5is a perspective view of one of said fasteners; Fig. 6 is a perspectiveview of the rock shaft and the two ratchet members or plates; Fig. 7 isa detail section taken on'the plane indicated by the line 7-7 in Fig. 1;and Fig. 8 is a perspective view of the cross-bar for the lace.

In the drawings, we have shown a bedstead or frame 1, of ordinaryconstruction, having head and foot pieces 2, 3 united by angle metalside bars or rails 4.

5 denotes a mattress supporting frame which is removably mounted on thebedstead or stationary frame 1 and which is covered by the usual elasticwoven wire fabric 6, or any other suitable elastic or flexible covering.The frame 5 consists of .a main or foot section 7 and a verticalswinging head section 8, which latter is united to the frame by straphinges 9 .or any other suitable pivotal connections. The section 7 ofthe frame 5 is preferably composed of two side bars 10 united by a crossor end bar 11 to which latter one end of the wire fabric covering 6 issecured by a clamping strip 12 in the usual manner. The head section 8is similarly composed of side bars 13 united at their inner ends by thehinges 9 and the bars 10 and connected at their outer ends by an end bar14 to which latter the other end of the covering 6 is secured by aclamping strip 15. The side bars 10, 18 are adapted to enter between theside rails 4 of the bedstead and the projecting ends of the bars 11, 14:rest upon the latter to support the frame 5 when its .two sections areextended in longitudinal alinement. The head section 8 is adapted toswing upwardly to an angular position and, when in such position, theinner part of the section 7 is supported from the side rails 4c byprojecting supports 16 preferably in the form of angle brackets 16secured upon the outer faces of the bars 10 adjacent to their innerends, as clearly shown in Figs. 2 and 3. The swinging head section 8 isadapted .to be locked in any .of its inclined or angular positions by aratchet locking device consisting of two swinging ratchet plates ormembers 17 fixed upon the ends of a rock shaft arranged transverselybeneath the inner ends of the bars 10 and mounted for rotation insuitable bearings 18 secured upon the bottom faces of said bars 10. Theintermediate or central portion of the rock shaft is bent intosubstantially U-form to form a crank handle or loop 19 by means of whichthe ratchets 17 may be conveniently operated. Said ratchets 17 are inthe form of metal plates or strips having their free ends formed withratchet recesses or notches 20 and thus serve as fixed pawls or keepersfor .the ratchet members.

'It will be seen that when the crank loop or handle 19 is swung towardsthe head .of

the bed, the ratchet members 17 will be lifted in the combined guideloops and keepers 21 to release the head section 8 which may then beswung either upwardly or downwardly, and that when the ratchet notches20 in the members 17 drop over the lower portions 22 of the keepers thehead section will be secured in adjusted position.

When the covering 6 is in the form of elastic woven wire fabric it isstretched tightly over the frame 5 when the two sections are inlongitudinal alinement with each other so that when the ratchet deviceis operated to unlock the head section the elasticity of the springcovering 6 will elevate the head section 8. To support the portion ofthe covering 6 above the section 7 of the frame 5 in a substantiallyhorizontal position when the head section is elevated, we provide aconnection between said covering and the inner end of the head section.This connection is preferably in the form of a flexible strip 23 ofleather or the like laced back and forth between the covering 6 and theperforated cross bar 24 arranged beneath the inner'portion of the headsection 8 and having its ends secured to the side bars 13 of the latter.

For the purpose of preventing the section 7 of the frame 5 from tiltingwhen the head section 8 is in an adjusted angular position, we providesuitable fasteners, preferably in the form of turn buttons 25 pivoted,at 26, upon the projecting ends of the bars 11 and adapted to swingunder the inwardly projecting flanges of the angular side rails 4 of thebedstead, as clearly shown in Fig. 4. If desired, we may provide similarcatches or fastenings 27 upon the projecting ends of the bar 14 tosecure the head section 8 in a horizontal position on the bedstead.

From the foregoing it will be seen that our invention is simple, andpractical in construction so that it may be produced at a comparativelysmall cost and will be strong and durable in use. It is also exceedinglyconvenient in operation, and may be adjusted by the occupant of the bed.

While we have shown our improved bed spring mounted in a bedstead ofordinary construction it will be understood that it may be embodied in abed, couch, or similar piece of furniture of any form and construction.It will also be understood that various changes in the form, proportion,and minor details of construction may be resorted to without departingfrom the spirit or sacrificing any of the advantages of the inventlon.

Having thus described our invenion what we claim is:

1. The combination of an adjusta e frame having hingedly connected footand head sections, a covering for the frame attached to the outer endsof its sections, a cross bar arranged beneath the inner portion of thehead section and having its ends attached to the sides thereof, theintermediate portion of said cross bar being offset and formed with alongitudinal series of apertures, a lacing stra laced back and forththrough said covering and the aperand keeper loops 21 upon the sidefaces of the side bars of the head section, the ratchet plates 17 fixedto said shaft and adapted to project through said loops, the bottomedges of said plates being formed with a series of ratchet recesses todrop by gravity into engagement with the lower portions of said loops tolock the head section in an adjusted angular position and a crank handlefor actuating said shaft.

3. The combination of an adjustable frame having hingedly connected footand.

head sections, each consisting of side bars united by end bars, acovering for the frame attached at its ends to the end bars of thesections, a connection between the intermediate portion of the coveringand the inner end of one of the sections, bearings upon the side bars ofthe foot section, a transverse shaft journaled in said bearings andhaving its intermediate portion offset to provide the crank handle 19,the keeper loops 21 fixed to the side faces of the side bars of the headsection and the ratchet plates 17 fixed to the ends of the shaft andarranged in said loops, substantially as and for the purpose set forth.

at. The combination of a stationary rectangular frame, an adjustableframe having hingedly connected foot and head sections, each sectionconsisting of side bars united by end bars, a covering upon theadjustable frame having its ends attached to the end bars of itssections, a connection between the intermediate portion of the coveringand the inner end of one of said sections, means for adjusting the headsection angularly with respect to the foot section, the angle brackets16 on the side bars of the foot section to rest upon the top of thestationary frame and support the inner end of the foot section, theouter end of the latter being supported by the engagementof theprojecting ends of its end bar with the top of the stationary frame andthe turn buttons 25 at the outer end of the foot section to hold the latter down upon the stationary frame and pre- LEWIS S.
